I'm trying to figure out a power solution for my 5,1 Mac Pro and Titan X GPU. Can anyone tell me what this port, marked "ODD PWR" provides? It looks like it is the port that provides power to the 2 SATA ports located in the optical bays, but am hoping somehow with more knowledge can confirm such. If so, wouldn't it be possible to run a cable from this port to the 6pin connector of a GPU to provide power that way? I am looking to use a dual mini-6pin to 8pin cable, so am looking for ways to power the other 6pin port of my GPU. I was going to use a dual 15pin SATA to 6pin cable and run it from the optical bay power, but then figured that power has to come from somewhere on the logic board. Is this port it?
